They just did a 'Duck Dodger' revival on the cartoon network, and it didn't go over that well. I'm guessing they feel that it did well enough to justify brining out the entire line.
It will be hard to write now though, many of the funniest Loony Toons depended on relentless slapstick violence that would attract problems now. And the various cross dressing bits that Bugs did would be right out.
